Salary NegotiationCalculator

This calculator uses a dual-compounding model. First, it compound-grows the initial negotiated salary difference using your annual wage growth/raise rate (g) because percentage-based raises apply to the higher base salary. Second, it compound-invests each year's accumulated cash difference at your expected investment return rate (r). This represents the full career wealth impact of negotiation.

The 3.4% default raise rate is based on the seasonally adjusted civilian wage and salary increase reported by the U.S. Bureau of Labor Statistics (BLS.gov) for the 12-month period ending March 2026. The 7% investment return rate is a standard inflation-adjusted real return estimate for a diversified equity portfolio (historically ~7% real yield for the S&P 500).

Research shows that most employers leave 10-20% headroom in initial offers, and successful negotiations typically add $5,000 to $15,000 to starting base salary. For job changes, the difference can be larger. Use the number that matches your specific situation or target negotiation outcome.

No. This calculator models pre-tax growth for simplicity. Real after-tax returns would be lower depending on your tax bracket, investment account type (taxable vs. tax-advantaged), and state of residence. The model is designed to illustrate the magnitude of the negotiation opportunity, not to provide precise after-tax projections.

The salary paycheck calculator shows your take-home pay after taxes and deductions. This calculator shows the long-term compound value of a salary negotiation difference — how much that extra income grows when invested over your career.
